The Dfiner is indicated for catheterization of the male urethra for the introduction of contrast materials.

The Dfiner Urological Catheter is a dual lumen flexible co-axial catheter. The main lumen contains a flexable sheath which houses is a solid flexible rod. Attached to the distal end of the rod is an array of wires. The wire bundle can be advanced and deployed in the bladder to assist with anatomical imaging. Contrast material is introduced through the main lumen. The catheter has a rigid "Y" connector at the proximal end that allows the wire bundle/sheath to be deployed/retracted and access to the main lumen.
